Features

01Dust control for dry graphite cuttingA sealed roof collects dust from dry machining and an air curtain keeps fine dust out of each axis. The door design makes cleaning and draining slideway lubricant easier.
02Dust collector standardThe dust collector uses 12 cartridge filters with a 50 m² filtering area and automatic air-pulse cleaning, driven by a 3.7 kW motor.
0320 kW built-in spindleA dust-proof and waterproof 20 kW built-in spindle runs to 20,000 rpm with a BT-40 taper; the catalog lists CAT40 and HSK-E63 as options. Bearings are grease lubricated and the spindle is oil cooled.
04Double column with wide LM guidesThe double column frame runs wide LM guides on X, Y and Z, with servo motors coupled directly to high-precision ball screws.
0516-tool servo magazineThe fixed-address rotational ATC is driven by a servo motor and holds 16 BT-40 tools up to 200 mm long and 8 kgf. Larger magazines up to 32 tools are optional.
06800 kgf tableThe 1,300 x 800 mm T-slot table carries up to 800 kgf, with 80 to 580 mm from table surface to spindle nose.
